Introduction to Programming

To simplify programming an angle, corner radius, or chamfer between two
lines, all that is necessary is the angle between the lines and the radius or
chamfer size connecting them. This method of programming can be used
to simplify the cutting of many complex parts.
QuickPath words are made up of the addresses below followed by the
desired numeric value.
If you see: It means:
,A angle
L length
,R corner radius
,C chamfer size
Important: A comma “,” must precede the ,R and ,C address characters
for the control to recognize them as radius or chamfer words.
For more details and examples using these words, see chapters 16 and 17.
An F-word with numeric values specifies feedrates for the cutting tool in
linear interpolation (G01), and circular interpolation (G02/G03) modes.
The feedrate is the speed along a vector of the commanded axes, as shown
in Figure 10.5.

The term “feed” refers to moving a tool at a specific velocity in a cutting
path. “Feedrate” is the velocity programmed for the feed of a tool.
